Abstract

Column redundancy data is selectively retrieved in a memory device according to a set of storage elements which is currently being accessed, such as in a read or write operation. The memory device is organized into sets of storage elements such as logical blocks, where column redundancy data is loaded from a non-volatile storage location to a volatile storage location for one or more particular blocks which are being accessed. The volatile storage location need only be large enough to store the current data entries. The size of the set of storage elements for which column redundancy data is concurrently loaded can be configured based on an expected maximum number of defects and a desired repair probability. During a manufacturing lifecycle, the size of the set can be increased as the number of defects is reduced due to improvements in manufacturing processes and materials.
